1 Scope This document applies to laboratory model tests of any type of Pelton hydraulic turbine. This document applies to models of prototype machines with unit power greater than 5 MW. Full application of the procedures herein described is not generally justified for machines with smaller power. Nevertheless, this document can be used for such machines by agreement between the purchaser and the supplier. This document excludes all matters of purely commercial interest, except those inextricably bound up with the conduct of the tests . This document is concerned with neither the structural details of the machines nor the mechanical properties of their components, so long as these do not affect model performance or the relationship between model and prototype performances. This document covers the arrangements for model acceptance tests to be performed on Pelton turbines to determine if the main hydraulic performance contract guarantees (see 9.2) have been satisfied. It contains the rules governing test conduct and provides measures to be taken if any phase of the tests is disputed. The main objectives of this document are:
to define the terms and quantities used;
to specify methods of testing and of measuring the quantities involved, in ...
